Hey a 7.9 score rates "Good", but Cateye had to be hoping for better. The whole idea of gaming and working out seems a little obtuse. Still, we applaud any effort to improve our dismal exercise routine. The reviewer did like the fact that the bike makes working out more fun.
Of course, it's meant to be played with racing games — the pedal acts as the acceleration button, and the handle does wheel chores. For the most part, GS likes the execution on this front — though some games are not compatible with the bike. They also didn't like the fact that more complex racers (with stunts or tricks) are tough to control. It looks like that last point is what knocked off the most points.
